The purpose of this statement is to provide a quick reference for the capabilities
of OSL's E&P team, Capability and Capacity.
OSL Rail was established in 2010 to provide signalling and multi-disciplinary
engineering, technical and project delivery support and consultancy services
to clients in the UK and internationally. Since company formation we have
rapidly established ourselves as one of the leading independent signalling
design and testing companies in the UK market and we are currently working
towards achieving similar status outside of the UK.We have worked on a range
of major high profile rail industry projects and programmes in a variety of roles.
An exemplary track record has led to OSL becoming the delivery partner
of choice with many major rail industry companies on both the client and
supply-side.

• Fifteen (15) designers
(of various status and qualifications)
• Supported by four (4) Graduates and (15)
technician Grades
• We have a growth plan and strategy to increase

alone and ten (10) both in Crewe and Swindon.
Covering (but not limited to) the following disciplines:
• Electrical,
• Mechanical,
• Civil,
• Structural,
• BIM, 2D 3D CAD
The team structure supports:
• CRE’s,
• CEM’s, that can cover across the disciplines to
manage the multi-discipline design delivery.
• Principal, Senior and Design Engineers,
• CAD and technician levels
In addition to the above,OSL are able to undertake
Building services, MEICA and process design for
Water, Waste Water, Energy from Waste and
both commercial Industrial and buildings from the
Warrington office. This allows OSL to undertake
station works and refurbishments.
Skill / Experience
Our core team has strength in EP design and
the project management of installations, with a
recent addition of installation and testing divisions.
OSL have developed a skills matrix to ensure we
are able to undertake all the areas of EP with
depth of named labour to ensure designs are fully
developed into construction drawings and not
simply just proposals.
development of resource
OSL have developed a structured training
programme to acquire and train resources of
varying skilled backgrounds directly from other
industries as well as developing apprenticeship
and graduate training schemes.
With resources situated nationwide, OSL currently undertake the majority of
all EP and fixed plant design from the Warrington office with manufacture,
installation and management capabilities based at Crewe. We also carry out
EP Design in both Swindon (Wiltshire) and Crewe (Cheshire) in support of
other discipline lead projects and to provide resource toWarrington. OSL also
plan to open an office in Stevenage (Hertfordshire) and locations to be advised
inWales, London and the East of England.
“OSL have a solid reputation for
delivery, quality, and an integrity
that results from years of building
relationships with our clients”
capability
Our long-term aim is to train up future resource from
the grass- roots to provide a stable resource pool to
the benefit of OSL and the Rail industry as a whole.

design
The EP team has been involved at all levels of GRIP
design and covers the following areas:
• Signalling Power supplies
• Functional Supply Point cabinets
• Signalling Supply Point/ PSP, including enclosures
• Auxiliary Power Supply Points, including enclosures
• LV and HV substations
• Cables sizing and routing
• Points heating
• Lighting for; depots, track side and stations
• Building Services for; stations, switching building,
ancillary track buildings
• Lifts and escalators
• CCTV system and networks
• Minor civils for EP structures
• Integration with SCADA
• UPS Design
• DNO power supply upgrades
• REB Upgrades.
The OLE Survey capability is supported by our use of a 360-degree camera
system, which we use to provide a view unique to the site. The 360 view
assists with design and can be annotated with information and measurements
made from the view and captures used for reporting and directly importing
into BIM tools.
The ease of date interpretation results in upmost efficiency. A major benefit
of the package is the health and safety application of using it in locations to
reduce staff visits.
Installation Testing
OSL have a team that can install and test the work
designed by the EP designers either in-house design
or external design.
Our construction teams are led by –
• Two (2) construction CRE’s, and supported by
• Eighteen (18) strong team leaders and installers.
Our Test and Commission team comprise of –
• One (1) Level A,
• Two (2) Level B’s,
• Several Level C and D authorised personnel.
Enabling us to access,undertake isolations and work
on HV Substations.
We are in process of developing further Payee staff
to enable them to undertake Level B courses and
provide them (through our partners and clients)
sufficient switching experience to maintain their
logbooks and competences. Our commissioning
team of five (5) supports all of our works and are
a progressive addition to our signalling TC team.
